You do not have to say anything. But it may harm your defence if you do not mention when posting something which you later rely on in quote. Anything you do say may be ripped to sh*t.
Went about 20 years ago so cant give ideas on hotels. however if you are into art, old buildings, and "La dolce vita" it is the biz, spent a few days there and loved it.
Casa buonaorotti is a museum of Michelangelo's works, not very big but worth a look if you can. If you have loads of time then the Uffizi Gallery is fantastic, but you have to really be into art!
Been there many moons ago in the Spring for the fashion shows with Iranians - got arrested, long story. Great place when there aren;'t lots of tourists. Great culture and night spots and places t eat - Smallish city like Amsterdam that you can wander about on foot and find what takes your fancy. Lots of beautiful people that make English folk so mousey.
It may be that your whole purpose in life is simply to serve as a warning to others.
